I'm not sure what you mean by "before the adapter".
When I told the technician that I wanted the model that doesn't require a 6 pin he glanced at me and said there's no such thing, and that every graphic card needs a connector.
And I remember him mentioning something about my PCI being too old.
In general, never take your PC to a "technician". There isn't anything on a PC that is so hard that someone here couldn't explain to you what to do.
The 750 is an easy card to install. It's similar to a ram upgrade.
oddly enough, I've never met a person that worked at/ran a PC place that was competent in PC knowledge about parts. Well, competent I guess compared to the average member on a PC tech forum.
